Bryozoan fragments are very rich in flints found in glacifluvial sediments in the sandpit near Fukov. Due to the very specific preservation only 16 taxa have been determined – seven cyclostomatous and nine cheilostomatous. Cyclostomatous genera Mecynoecia and Crissisina volumetrically dominated. Among cheilostomatous fragments Onychocella and Coscinopleura are the most common. The lower Paleocene - Danian age is proposed due to the found of Coscinopleura cf. angusta and other genera characteristic for Tertiary.
